Abstract: Systems and methods are provided to enable secure remote activation and/or unlocking of content or other media assets protected using one or more copy protection mechanisms or techniques. Existing trusted processor architectures used by electronic devices (e.g., HD-DVD or Blu-Ray optical disc readers) can be used to allow remote activation and/or unlocking of protected content. An authorization server is configured to identify the specific copy of the protected content or other media assets at the device from the request, and determine the correct correlation between the request and information that enables the device to initiate playback of the protected content. Accordingly, the authorization server maintains secret or private on the authorization server the information that can be used by other parties to obtain a correlation between the request and any response received from the authorization server that enable the device to initiate playback of the protected content.

Abstract: In various embodiments, systems, methods, and computer-readable storage media are disclosed for generating content streams that conform to the Blu-ray Specification. In some embodiments, to provide true live streaming of content that conforms to the Blu-ray Specification to platforms that conforms to the Blu-ray Specification, one or more content stream creation devices (e.g., A/V encoders and multiplexers) are passed information on how the output file for a transport stream should be formatted. A plurality of Clip Information files may be used to create the transport stream for the content. Platforms that conform to the Blu-ray Specification may be configured to select which one of the plurality of Clip Information files were used to create all or a portion of the transport stream and use that Clip Information file during playback.
